Functional Description
If (ELSnB:ELSnA = X:1), then the channel (n) output is forced low at the channel (n)
match (FTM counter = CnV) when counting down, and it is forced high at the channel (n)
match when counting up (see the following figure).
If (CnV = 0x0000) or (CnV is a negative value, that is, CnV[15] = 1) then the channel (n)
output is a 0% duty cycle CPWM signal and CHnF bit is not set even when there is the
channel (n) match.
If (CnV is a positive value, that is, CnV[15] = 0), (CnV ≥ MOD), and (MOD ≠ 0x0000),
then the channel (n) output is a 100% duty cycle CPWM signal and CHnF bit is not set
even when there is the channel (n) match. This implies that the usable range of periods
set by MOD is 0x0001 through 0x7FFE (0x7FFF if you do not need to generate a 100%
duty cycle CPWM signal). This is not a significant limitation because the resulting period
is much longer than required for normal applications.
The CPWM mode must not be used when the FTM counter is a free running counter.

= 0x0000.
